#6 : 5 #

Explanation:

The current gap between the ratio is 1. There are six more boys than girls, so multiply each side by 6 to give #24 : 18# - this is the same ratio, unsimplified and clearly with 6 more boys than girls. 2 extra girls join, so the ration becomes #24 : 20#, which can be simplified by dividing both sides by 4, giving #6 : 5#.
